Title: Grinding and fluidizing dryer installed to grinding and fluidizing drying apparatus
Inventor: IWANAMI SADAO
IPC: F26B3/08
Filed: 1991-03-22
Abstract: PURPOSE:To prevent that the foreign matter in a raw material enters a powder recover apparatus and is collected in a slide grinding part by installing a damper freely movable up and down to a tower part and making the bottom plate of the slide grinding part provided on the side opposed to the lower end of a chute freely openable and closable. CONSTITUTION:When foreign matter such as a metal piece or a small stone is mixed with a raw material, the foreign matter receives the rotatory power of a rotary impeller 4 to be given up toward a ceiling. At this time, when a damper 30 is lowered by operating a damper up-and-down moving mechanism 32, the given up foreign matter impinges against the damper 30 and can be prevented from entering a powder recovery apparatus through the duct provided to the ceiling. Since the foreign matter is bitten in the gap between the rotary blade 10 of a rotary impeller 2 and the inner surface of a slide grinding part 2, the load applied to the rotary impeller 2 increases. This load is detected by a detector to input an overload detection signal to the opening and closing drive mechanism 21 of an opening and closing bottom plate 2A and an air cylinder is subjected to shortening operation to open the opening and closing bottom plate 2A to discharge the foreign matter.

Title: Centrifugal pump
Inventor: UENISHI AKIRA
IPC: F04D15/00
Filed: 1982-05-21
Abstract: PURPOSE:To control the flow-rate efficiently and improve the partial load efficiency of a pump by installing a plurality of valves built-in the swirl chamber of a centrifugal pump and opening and closing these valves. CONSTITUTION:A butterfly valve 1 is installed in the swirl chamber of a pump, and said pump is separated into a pump in the valve upstream part and that in the valve downstream part, and only the flow-rate is varied without varying the pump head through the parallel operation of two units of the same pump. The pump in the valve downstream part is put into rated-operation, and the pump in the valve upstream part varies the operation point along a pump-head curve according to the opening degree of the valve 1. The above example represents the case of a pump whose valve is installed in the position where the flow is divided into halves, but any desired position can be selected. In other words, in the case when a small range of flow-rate control is permitted, the position is set at a position 2(Z2) or 3(Z3), and on the contrary, when a flow-rate control range of about 50% or so of the rated value is necessary, the position is shifted to a position 4(Z4), and the position is determined after taking account of the efficiency and the range of flow-rate control. Fine flow-rate control is permitted based upon the relation between the efficiency and the flow-rate, if a plurality of valves are provided, instead of only one valve.
